When driving in rain and high humidity, the windshield and front windows will often completely fog up with moisture on the inside of the car. It can make seeing outside while driving impossible and risks an accident. In three years we have found no settings on the climate control system that will avoid this problem. We have had the heater core replaced in a futile attempt to remedy the situation. We have been told by Buick that there is no fix or recall.

Defrost system not working properly, front windshield defrost system fails to clear window, and visibility is an issue. HVAC system doesn't cool properly, compressor comes on, however temperature only lowers to a certain temperature. Temperature cools better while vehicle is in motion on highway.

Electronic climate control system allows windshield to become fogged over and I cannot see to drive or control HVAC system. I cannot control the heating, cooling and ventilation. Example: The system seems to blow or allow warm air in cabin when the A/C is on set at 68-72 degrees. This is when car is in motion and at idle on any road I travel. I reported problem to rice Buick-GMC, Inc. 8330 kingston pike knoxville, tn 37919-5449 (865) 693-0610 on 9/16/2014, 9/25/2014 and the problem persisted & getting worse to date 01/07/2019. I just found out about this important safety recall. Safety recall is listed for 2011 Buick Lacrosse on March 4, 2011 NHTSA campaign number: 11V149000 software in electronic climate control affects defrost system reducing drivers visibility and could result in crash. Unable to control HVAC system. Second problem is engine/ emissions, catalytic converter, sensor errors. All have caused check-engine light to come on.

Sunroof exploded outward going 70mph on interstate. No cars around me no birds or other things. Road perfectly smooth straight direction of travel. No bad weather and all windows raised at the time. Scared me to death. Everything was normal up until the time it exploded. I thought it was a bullet at first.

I have issues with my defrost system in my 2011 Buick Lacrosse which is causing visibility issues (safety) when I drive. Several times I had to pull off the road, roll down my windows and try to get my windshield to defrost so I could see to drive. I looked up recalls on cars.com and noticed that there was a recall issued in March 2011 for 2011 Buick Lacrosse models for the ecc module describing the exact systems my car is having. I called the Buick 1-800 number to inquire about the recall and the representative stated that my particular VIN# was not on that recall list but I could take it to a dealership for a diagnosis and for repairs at my expense. I explained to her that I could not understand why if my car is having the exact same issues as the recall is stating why would my car not be under the recall notice. She stated that it was probably manufactured at a different plant and not at the plant which recalls were issued. My question is "if I am having the same exact issues as described in the recall for the 2011 Buick Lacrosse models than why do I have to pay to have the problem diagnosed and fixed?" I believe that Buick should take responsibility and contact a dealership to have my car diagnosed and then if it is determined that this is the same problem as the recall they should pay for those repairs as well. This has been an on-going issue since I purchased the car (used) in October 2014

Climate control system. On three occasions the climate control system has switched to heat and high fan, locking the driver out of the controls and causing the passenger compartment to become extremely hot and uncomfortable. I was able to pull over to the side of the road on one occasion, turn the engine off and let the car sit for a few minutes before restarting the car. The system returned to normal. On two of the three occasions, the car was in motion. On one occasion it happened in the garage. Dash lights - while driving at night, all passenger compartment lights went off for about 30 seconds, and then came back on. I took the car to the local dealer and they checked the system, including the battery. They found no computer codes to explain the malfunction.

Defroster, heat, A/C, fan speed, recirc, heat/cool seats functions failed (stopped working completly) while driving in a snow storm on January 12, 2016 on highway us 131 to traverse city, mi. Found recall information NHTSA # 11V149000. Brought to dealer. Dealer said not coverred under recal due to VIN #, and owner cost of $400 + to repair. Contacted Buick customer care. Spoke with asia and leslie on 1/15/16, who said GM could not help. I described language of the recall as being identical to the safety hazard described in the NHTSA language: "windshield defrosting and defogging systems" on these vehicles, the software in the electronic climate control module may disable the ability to adjust the heating, ventilation, and air conditioning system settings. If this happens, the driver will not be able to control the cooling and ventilation for the vehicle. Consequence: If this condition affects the defrost system when it is required, it may decrease the driver's visibility and could result in a crash."

Blind spot warning system (bsws) inoperative que on vehicle multi function information display (mfid), located behind the steering wheel in a 3"X4" area is inadequate. The bsws on this vehicle is very sustainable to road spray during rain events that renders this system inoperative. The issue is in the warning that is displayed to the driver when this occurs. The message displayed is only shown for approximately 5 secs, then is removed without any driver action acknowledgement. No icon is shown to remind drivers of active messages. If this message is missed, the driver is not aware that this system is inoperative. Also, there is no message telling the driver when this system becomes operational again. Two possible outcomes. 1. the driver does not believe in the system, losing the benefit of this valuable system, especially in this vehicle model with its large blind spots, or 2. the driver believing in the system and turns into traffic, not realizing that the system has become inop and unaware because of the missed message on the mfid. These are basic human factors issues that have been dealt with in the aviation industries for years. The industry needs to address these types of issues as we continue to increase our reliance on automation in these vehicles. The lack of a standard and standards between manufacturers will become a significant player in coming years.
